It's the first time the world-famous royal has been photographed since the Palace confirmed her pregnancy on Monday — when she checked in to be treated for Hyperemesis Gravidarium, an extreme form of morning sickness.

"The Duchess of Cambridge has been discharged from the King Edward VII Hospital and will now head to Kensington Palace for a period of rest," the Palace tells Us Weekly in a statement. "Their Royal Highnesses would like to thank the staff at the hospital for the care and treatment The Duchess has received."

During her three-night stay, the future Queen received frequent visits from husband of 19 months William, 30, plus her mother Carole and siblings Pippa and James, among others.
